The core idea
Stock quantities are never edited directly. You cannot type a new number into a balance. Instead you record an operation — an adjustment, a transfer, a count, a sale — and the balance changes as a result. This means every quantity has a history. When a figure is wrong, you can see exactly which operation caused it and who did it.What is here

The four core operations
Draft, then post
Every operation follows the same pattern:1
Create it as a draft
Add your lines. No stock has moved. You can edit or delete freely.
2
Check it
Right items, right quantities, right location.
3
Post it
Stock movements are written and balances update. This is the moment it becomes real.
4
It is now permanent
A posted operation cannot be edited. If it is wrong, void it — which creates reversing
movements and leaves both records visible.
Negative stock
By default Bumara blocks any operation that would take a balance below zero. If you try to sell or transfer more than you have, the operation is refused and tells you which item is short. This is usually right. A negative balance means your records have lost touch with reality, and carrying on makes it worse. An administrator can override the block where genuinely necessary — typically when goods have physically been received but not yet entered. Overrides require a reason and are recorded.Locations
Stock is held at locations — a main store, a shop, a warehouse, a vehicle. Every quantity is per item and per location. Your first location becomes the default. Users can be assigned to specific locations, and their dashboards then show only the stock they are responsible for.Units of measure
Bumara includes standard units — each, kilogram, litre, box and others. You can add your own, and define conversions between them, such as one box equals twelve each. Set the right unit on each item at the start. Changing it later, once movements exist against it, is disruptive.What links to invoicing
Products in Invoicing can link to inventory items by their code. When linked, selling the product moves the stock. Keep the codes consistent between the two, and the link works without further thought.Low stock
Each item can carry a reorder level. When a balance falls to or below it, Bumara flags it as low stock and can notify you. Set reorder levels on the items that matter — the ones you cannot trade without. Setting them on everything produces noise you will start ignoring.Where to start
